perpendicular to wall. Using pneumatic staple gun, staple pan at center V-groove and at flange of receiving end.

3. Cut soffit panels 3/8”-1/2” shorter than measurement from wall to face edge of 2x6 sub-fascia board. (See Figure 14-2) Do Not cut all panels at once withoutchecking measurement along house every 4’-0”. Sometimes the truss tailextensions are not the same along the wall.

4. Slip soffit panel into F-channel and nail to 2x6 sub-fascia board with 1- inchcolored nails or pneumatic staple gun if available with two nails per panel. One atcenter groove and one at flange of receiving end. Be certain to insert succeedingpanel securely into preceding panel so that panels run true across the eave. Usea framing square to ensure a quality installation as you install along the eaveevery 4’-0”.

5. Start installing the gable end soffit pieces at the peak. Put a bend atapproximately the middle of the piece. Install it into the F-strip, check with asquare to make sure you have a straight start and nail it in place using the 1”colored nails or staples.

6. When you get to the gable endboxed return, (See Figure 14-3), theJ-strip is installed at the last panel if the F-channel is not returned. Oneend of the J-channel sits in the F-channel and the other end will benailed to the 2x6 sub-fascia. The

fascia must be installed first at theboxed return. Figure 14-3

7. The bath exhaust fan grille will have to be installed as you are installing the soffitpanels. Where the duct is routed thru the heel of the truss, 24” on each side of the duct, the vents in the soffit panels must be taped off with clear Weathermatetape or use solid panels. This is to prevent moisture from getting back siphonedinto the attic. Cut out soffit to fit grille base allowing ¼” space for expansion. Nailone end of grille base to sub-fascia with 2 - 2” roofing nails. Slide in pan aroundgrille base and install grille cover.

8. Porch soffit panels are installed after the porch beams have fascia installed.

Refer to paragraph in section 14.3. Install F-channel at all four sides of inside of porch. Check to make sure there is blocking above beams and between thetrusses to nail flange in place. If the truss along the house was not held back 7½” as called for on the roof framing plan and is tight to house, you will have toeliminate the F-channel because you will not be able to nail it in place. In thiscase the siding J-channel will have to be installed so soffit panels sit on top of theJ-channel between the roof truss. Slide panels into F-channel. Hint at oppositeend at one side if the top flange of F-channel is cut and bent up, you can drop thepanels in place and slide over. Remember to bend flange back down beforeinstalling last panel. Nail the center of the panels to the bottom of the roof trusses

with the 1” white soffit nails. One nail at center of panel and second nail at flangeof receiving edge of panel. There will be a recessed light fixture to cut out

around. Allow ¼” space around light housing for expansion.9. For soffits that wrap around outside or inside corners, install H-channel on an

angle. Cut soffit panels at 45 degree angle and slide into channels.

14.3 Installing Fascia

1. Install 10” aluminum fascia first around the gable end boxed returns. This willrequire cutting 1 ½” off the bottom flange. Using metal brake bend at this pointso flange will be against gable end wall of house. Then measure over for thedepth of the boxed corner and make a cut at the bottom flange. Using metalbrake bend this piece at the cut to wrap around outside corner of boxed end.

This piece will then have to extend to the eave fascia board and cut flush. Thetop will have to be cut to follow the slope of the roof edging. It is acceptable tonail this piece at the top where gable end fascia will cover over the nails. SeeFigure 14-3.

2. Next install 6” aluminum eave fascia first starting at the back of the house sooverlaps are not seen from the front of the house. Cut off 1”-2” of the bottomflange away from the end of the fascia and bend a 1”-2” corner to fit over thecorner of the gable sub fascia with metal brake. Slide this flange under theboxed corner 10” fascia piece.

3. Push the fascia up under the gutter apron until the flange is snug to the soffit anddrive a soffit nail through the fascia flange and soffit V-groove into the undersideedge of the sub fascia with 1” white soffit nails. Install nails 20” o.c. or every fifthgroove. This prevents nails from showing on the fascia surface. Do not nailtightly; leave a ⅛” gap between the fascia and the soffit. Make sure fascia doesnot show “wrinkles” when installing. Be careful not to dimple the fascia with your hammer.

NOTE: Another option is to pre-drill ⅛” holes into the fascia flange throughthe soffit valleys.

4. Overlap the next piece 1” and nail as noted above. All fascia pieces need to be atleast 60” long. Finish the front of the house the same way by cutting off 1”-2” of the bottom flange away from the end of the fascia and bend a 1”-2” corner to fitover the corner of the gable sub fascia with metal brake and sliding under theboxed corner fascia.

On gable ends, start at the bottom of the gable so overlaps will enable rain towash off.

Cut the bottom flange off one end of the piece of fascia so it will extend to wherethe soffit panels start at the gable end. Cut the face of the fascia (the side wherethe gable and eave meet at the boxed corner) flush with the eave fascia. Install

by nailing through the flange as noted above. This piece will overlap over the 10”boxed in fascia.

5. Extend fascia until you reach the peak. At the peak the fascia will overlap. Thefirst piece of fascia will extend past the joint of the sub fascia to opposite roof edging. See Figure 14-4. This will require cutting away some of the bottomflange to fit. The piece of fascia running up from the other fascia board will becut to cover beyond the peak of the sub fascia and make a finished cutperpendicular to the peak. Nail through the flange to finish.

Figure 14-4

6. Installing fascia at porch beams.

Before installing aluminum fascia over beam, make sure beam width will beabout ½” larger than the flange that gets installed at the top of the vinyl porchposts. Add wood furring as required. Measure the width of the bottom of thebeam. Use aluminum coil stock and cut the strips in one continuous length for each beam section. Nail with the 1” white aluminum nails or staple in placekeeping the fastener within ½” from edge so it will be covered by the bottomflange of the fascia. Then using 10” fascia panels cover the 2x10 beam. Nail

panels with 1” white nails. Make sure the nails are near the top so they will becovered by the soffit f-channel trim. Then use sparingly the 1” white nails tohold bottom flange in place.
